摘要

当风力发电机组运行风速超过额定值时,风力发电机的输出功率会随风速的变化而产生波动。若功率波动处于较高水平,极易威胁电网的稳定运行状态。为解决这个实际问题,该文基于系统化的三步法设计了针对变速风力发电机在超过额定风速工况下的非线性功率控制器。该控制器由类稳态控制、参考动态前馈控制和误差反馈控制3个核心环节构成,且控制器增益是参变和状态依赖的。然后,基于输入到状态稳定性（ISS）理论对闭环系统的鲁棒性进行分析,并据此提出控制器参数的整定原则,将设计的三步法非线性控制器应用于水平轴变速风力发电系统中。仿真结果充分表明所提控制策略能够适应风速的大范围变动,实现风力机功率的平稳输出,且对风速扰动具有良好的抑制作用。

Abstract

When the wind turbine power system works above the rated wind speed,the disturbance of wind speed can cause the output power fluctuation, which can influence the stability of the grid. In order to solve this actual problem, a nonlinear controller based on the systematic triple-step method is designed for the power control problem of variable speed wind turbines （VSWT） above the rated wind speed. The controller includes steady-state-like control, feedforward control based on reference dynamics and state-dependent feedback control. The controller gains are parameter-varying and state-dependent. Then, based on ISS theory, the robustness of the closed-loop system is analyzed and the selection principle of the parameters of the triple-step nonlinear controller is given. The triple-step control strategy is applied to the power control of the horizontal axis VSWT. The simulation results show that the triple-step nonlinear control strategy can accommodate the wide-range wind speed variations, achieve stable power output, and exhibit an excellent suppression capability for wind speed turbulence.
